The Effect of Organic Matter on The Soil Innoculated Mycorrhizal on The Persentage of Root Infection and Growth of Mung Bean Plants

This study was conducted to analyze the effect of organic matter application on mycorrhizal
inoculated soil on the percentage of AMF infection and the availability of phosphorus nutrients
for the growth of mung beans. The research was conducted at the Green House, Universitas
Muslim Indonesia, and in the Microbiology laboratory of the Environmental and Forestry
Research Institute, Makassar, which was carried out from May to August 2021. This research
was conducted in an experimental form based on a completely randomized design consisting
of four treatments with three replications. The treatments tested were planting media, namely
sand + soil (without organic matter), sand + soil + husk, sand + soil + husk charcoal, and sand
+ soil + husk + husk charcoal. Parameters observed in this study were total soil P nutrient
content, available P content, percentage of mycorrhizal infection, plant height, number of
leaves, root length, and root volume. The results showed that the percentage of root infection
with the application of organic husk material obtained the percentage of root infection up to
83.67%. Plant growth and nutrient levels of total P and available P were higher with the
application of husk organic matter and husk charcoal.
